Artificial inoculation


Artificial inoculation technique already been developed and is found to be most effective and reliable method for enhancement of agar production. Works on commercialization are in progress and expected to make available for general use in the field.

The Agarwood created by artificial inducement is called Cultivated Agarwood or Induced Agarwood. Artificial inducement technique (or Agarwood inducement) consists of two actions: to wound the tree and to pour stimulative agent into this injury, this stimulative agent hereinafter referred to as inoculant. Quantity and quality of cultivated agarwood surrounding the injury depends on the composition of inoculant and the method of transfusing inoculant into the tree.

Nowadays, there are about several tens of inoculants whose composition is kept secret. But in general the main components of inoculant are:

  • Some fungi and microfungi, for example: Fusarium oxysporum Schlecht., Cladosporium spp, Cercosporella spp, Aspergillus Phoenicis (Corda) Thom & Currie, Cytosphaera Manganiferae Died, Melanotus flavolivens (BerPlant hormonesk. & M.A. Curtis) Singer, Penicillium Citrinum Thom, Chaetonium globosum Kunze, Phaeoacremonium parasitica,…in which Fusarium, Cladosporium and Cercosporella are three of 17 fungi that were found in 9 natural agarwood samples collected from the forest in Thailand, Fusarium and Chaetonium are two fungi found in natural agarwood pieces collected from India.
  • Some phytochemicals, phytohormones namely: salicylic acid, ethephon, methyl jasmonate, chitosan, sodium bisulfite,..
  • Some bacteria, yeast extracts, plant nutrient media and plant regulators

Two main methods Agarwoodof transfusing inoculant into Aquilaria tree:

Dispersing wounding by mechanical injury: to drill several tens (20-100) of hole into which the inoculant is poured. In this case induced agarwood is formed around these spot injury sites. The resulting agarwood from the localized formation is usually in the form of thicker wood chips.

Internal wounding: to transfuse inoculant directly into tAgarwoodhe xylem vessels of tree by using transfusion set, in this case only few holes are needed. If the internal wounding technique to be applied then induced agarwood is formed in whole tree along the xylem, from root/base up to the top of the trunk in a systemic manner, but relatively thinner formation of resinous wood.

Lately, inoculant operators have adopted to Dispersing wounding, leaving the Internal wounding for few reasons after gaining numerous field experiences … wood rotting is the main drawback.


wood rotting by internal wounding

While internal wounding is preferred by certain people, it can be further improved with “Pressurized method”. The air pressure can be portably pumped range 0.5 ~ 1.5 bar, hence minimize local concentration which resulting in tissue rotten. For cost effective, unit can be connected to multiple points, and reusable in next application. This invention is simple, inoculation process completed at faster time, no ingress of rain water even the injection holes are not sealed. Click “Mini pump“.

Dispersing wounding, tree drilling and chemical injection.DSC_4217-Edits800

This effort involves drilling of trees and keeping the wound open by placing a small piece of plastic pipe in those holes followed by a chemical injection to stimulate tree defense mechanism that produces resin. The first project of this effort was initiated in Vietnam under a supervision from Prof. Robert Blanchette, a wood pathologist from the University of Minnesota who together with local farmers and Buddhist monks. They developed experimental plots to stimulate the production of agarwood and after years of trials, this treatment yielded agarwood. Dr. Blanchette stated that this artificial induction could yield agarwood ten times faster than natural formation (WWW page: This finding has gained appreciation and has been considered as one of the most successful finding (Persoon, 2007). This treatment causes tree to respond in two defense mechanisms, physical and chemical. The first is phloem cells form callus and the second, should callus formation is prevented, the tree produces resin.

Dispersing wounding with 10~20ml liquid inoculant, some inoculant service providers utilize upto 100ml per treated hole.

The formation of agarwood is a result of plant defense mechanism towards fungal attacks by producing resinous compounds as secondary metabolite. In their natural habitat, the process of resin accumulation as the result of tree-pathogen battle may take many years and the longer the process takes place the more expensive and highly valuable the resin is. Many scientists have been passionately trying to understand the cascade process of this tree-fungi interaction in producing gaharu. Isolation of various fungi from infected trees have been widely reported.

Surface Inducement Technique ( Agar-SIT )… inoculant is designed to brush on the tree trunk. This technique allows easy agarwood collection, a considerably high yield and good resinous of agarwood could be harvested, along with the sustainable agarwood formation from the same tree. Specifically, this technique is aimed for oil production. Click “Agar-SIT-105” for detail …

Artificial fire method, China人工火烧法It is to burn the live agarwood tree with a large fire, forcing the agarwood tree to be injured. It looks very cruel, but it does not let the agarwood tree die, so the agarwood tree will mobilize the resin secreted by the immune system to heal the fire, and eventually form agarwood. Select the older tree, peel off the bark from the tree, leave the top leaves, and then use  gas torch to burn the whole tree and burn it black. This method is derived from the natural fire or the process of lightning strikes. The agarwood produced in this way is mostly thin, it is used a lot to produce incense.

inoculationIn China, newer species of Kynam has been successfully grafted, this species requires mechanical stress without any injection of liquid inoculant to produce resinous agarwood. Application of soldering device is sufficient for the job. However, the seedlings demand extremely premium price for the moment, click “Kynam









Planting money (Agarwood) trees doesn’t come without its challenges. One of these challenges is the inoculation. The Aquilaria tree has to be induced with a infection to induce production of agarwood (the resin), otherwise the tree would be quite worthless. Not all Aquilaria trees produce agarwood, they have to be infected by a certain kind of stress before they start “fighting back” with resin production to counter the infection. And even so, there is no set volume in the resin production (meaning each tree will produce its own amount).

Newbies blinded by the agarwood get-rich-quick scheme are often scammed through these so-called high quality inoculant which “guarantees” high rates of return. Till today, techniques are still being improved to artificially induce optimum agarwood production. There are “many roads that lead to Rome”, with trial and error being part of the journey but there are no guarantees.

The inoculation cost for a 5-8 years old tree in Malaysia ranges 30 ~ 50USD /tree inclusive labour (Time of writing … Dec 2018). Being a layman grower, this can be an astonishing figure if you have 1000 trees to inoculate.

Try this idea …. success

This product is available in local market (Malaysia), but it is sold under different trade name, it is mainly used to treat Durian disease, such as Canker. Phosphite is used as a biodegradable fungicide to protect plants against Phytophthora dieback. Phosphite (PO3) molecules, which move systemically via the phloem and xylem to the leaves and roots. This means that an entire plant receives many benefits of the phosphite molecule. With phosphite, a plant’s natural defense mechanisms are heightened … Phosphite encourages the nucleus of a plant cell to produce defensive molecules such as phytoalexin, which defense the tree from attacks by external intruders … you may try this at higher dosage to blend your inoculant recipe.

Are you running low on budget and NOT resourceful to do the trial … check for this “Option

Do not judge the book by its cover…. whether the inoculant is purchased from 3rd party or home-made, judging on the outlook of cultivated wood alone is insufficient without performing the oil analysis. To analysis the content of VOCs in “cultivated agarwood” we have to extract its essential oil and make GC-MS analysis on this essential oil for seeking specific compounds of natural agarwood. Click “Oudh quality” for detail … and NEVER proceed with mass inoculation without understanding the content of GC-MS report.

    dear sir,
    Your post is really helpfull and very informative.
    from bangladesh, how i can get ICU inoculant and how much the price?

    • tshinkou says:

      I suggest to use “Bamboo stick”, many types of inoculant available in the market, you really have to do your own survey. I have seen Bamboo stick result, it is proven.

      • Ripal Chakma says:

        dear tshinkou, thanks a lot for giving me your valuable advice. but i m from khagra chari hill district, which is very remote area of bangladesh. i really don’t have any idea of “Bamboo stick”.
        can i make ” Bamboo stick” by using local bamboo? if i can’t,then how i can get this n
        how much?
        thanks again.

  2. tshinkou says:

    These Bamboo sticks have been soak with unique inoculant a day or 2 prior to delivery by manufacturer. ICU method will cause rotten in the tissue, you still get the gaharu but harvest is reduced, The shape of gaharu is hollow in the middle. Pls click “” for Bamboo stick detail.

  3. NUr Sakinah Ismail says:

    how long does it takes to see the result for each technique?

  4. tshinkou says:

    Most of the techniques recommend a minimum 2 years for better result, the idea is, longer waiting time better the quality.

  5. Kenneth Wu says:

    Hi Tshinkou,

    Very informative website but I can’t find the name of Bamboo Stick manufacturer in the products catagory. Please let me know the name and the address of the manufacturer. Thanks.


  6. tshinkou says:

    The invention of such product is definately not from the big corporate. Many Agarwood growers claim thier products are the best, seriously i have tried few inoculants, and awaiting for the result.
    However i have seen the Bamboo stick “Cultivated Agarwood” in mass production, that why i am sharing my thought here that Bamboo stick might be one of the priority in the consideration list.
    Try a pack or 2, result will tell which is the best, happy surfing.

  7. Francis says:

    Thanks, your website is very informative. May i know the supplier of Bamboo Stick inducer in Malaysia.

    • Johny thomas says:

      Dear Sir,
      I am interested in bamboo Stick inducer.
      I have only one tree of 13 years old. Recently only I came to know about the value of it.
      How many sticks I have to use?
      Can you reply with details

  8. CJ says:

    can i know what are the inoculant use for the agarwood

  9. tshinkou says:

    Dozen of Inoculant available in the market, they are mainly home-made products. Unable to tell what are they. You can invent one of them and name it with your commercial name. Seriously, everyone claim their products are the best.

  10. Htun Wai says:

    Thanks, your website is very informative.

    • tshinkou says:

      Many veteran players refrain themselves from sharing their knowledge and hard-earned experiences, and hardly you will bounce to them in the net.

    • Htun Wai says:

      I would like to know agarwood inoculation with EM 1 method is a best one.

      • tshinkou says:

        Effective Microorganisms or EM is a mixed culture of beneficial microorganisms that can be applied as an inoculant to increase the microbial diversity of soils. This in turn, can improve soil quality and health, which enhances the growth, yield, and quality of crops.

        EM, my recommendation here is to promote plant growth. I don’t mean to inoculate the tree with EM, but you may try EM1 coupled with your own recipe.

  12. Mr. Zul says:

    Hi Mr. Tee,
    That mean inducer better than inoculant technique? is it bamboo stick can be used for any species of aquilaria?

    • tshinkou says:

      Each method has its unique Pros and cons, but inducer way is the improvement method from the inoculant after years of experience of the inventor. Yes, regardless of the species.

  13. Azwaj says:

    Thanks a lot for your very informative page.
    We have gone through your impressive page while browsing latest inoculation techniques for our agar plants which have become matured. You are, perhaps, aware of Bangladesh and we have about 60,000 agar plants. We need to start inoculation in coming monsoon. In Bangladesh, nailing is the only traditional way of doing this. Although CA kits have been applied in earlier years, it could not bring any success rather damaged most of the inoculated plants.
    Based on your experience, modern technology & all the other aspects, it would be great if we can get your kind advice and assistance regarding Agar Inoculation Techniques that can be followed by us in Bangladesh in the upcoming days.

    Would like to receive your reply at your earliest convenience.

    Bamboo sticks method is an improvement version to Liquid Inoculation when the inventor founf much rotten occured to the tree which further reduced to yeild, the inventor finally adjusted the dosage to suit field application. This does not indicate that liquid inoculation is too bad to be used, it is up to each individual to judge by himself which method suits him.

    Hello Tshinkou, How are the prices iike for artificially induced agarwood vs naturally produced agarwood (end product i.e. wood chips), also in quality will the artifically induced come close to the natural one?

    • tshinkou says:

      As long as natural wood supply is avialable and buyers are able to pay….. cultivated wood may need some time to find its room in the market …most probably next 10 years, when the natural wood stock in the middle east warehouse is depleting.
